Aiming at the problem of the data transmission reliability of the transmission network, a multi-path transmission protocol is put forward based on the degree constrained shortest transmission multipath transmission protocol of the tree, the protocol implements that each node in the network has two unrelated paths to reach the sink and the distance of transmission is shortest. At the same time, the number of child nodes is constrained, which reduces the occurrence of “hot spots”. To solve the deployment of multi sink nodes in the network problem, middle position optimizing strategy and edge location optimization strategy are put forward, and the robustness and load balancing of the network are analyzed. The experimental result proves that the network has good performance of the robustness and anti-interference, which is based on the multi-path transmission protocol. %U http://cea.ceaj.org/EN/10.3778/j.issn.1002-8331.1601-0058
